Sad. Currently @kenium 's trick doesn’t work for me. It fails on error: “TypeError: Cannot read property ‘t’ of undefined”. Here is the complete code of component: <template> <q-table :title = “$t(‘default.register’)” :data = “tableData” :columns = "columns" row-key = “startingNumber” /> </template> <script> export default { data: () => ({ columns: [{ name: ‘startingNumber’, field: ‘startingNumber’, label: this.$i18n.t(‘startingNumber’), }], tableData: [{ startingNumber: 1, }], }), }; </script> <style> </style>
